Wabco 1811140170 Side Skirt

Description

The Wabco 1811140170 Mid Skirt is a crucial component within trailer air brake systems, specifically designed for steering axles. This part functions as an aerodynamic element, enhancing airflow around the trailer's wheels. It is a left-side mounting component with a total length of 2.7 m. This mid skirt contributes to improved fuel efficiency and stability by reducing drag and optimizing airflow, resulting in a more efficient and controlled braking system.

Key Features & Benefits

These are primarily for aerodynamic improvements. They basically fill in the space between the trailer and the truck’s tires. They reduce turbulence and drag. Some designs also help with spray suppression, keeping road grime from getting up onto the trailer or other vehicles. They aren't directly a braking component even though you find them listed with brake controls, it’s more about overall trailer efficiency. Think of it like this: without a side skirt, air is rushing around and under the trailer, creating a lot of resistance. The skirt smooths out the airflow, kind of like giving the trailer a more streamlined shape. It’s attached to the side of the trailer, running along the length between the tires. They aren't load bearing, so they don’t affect the trailer's suspension or weight capacity, just how it moves through the air.

Symptoms, Risks & Replacements

The biggest thing is fuel savings. Reducing drag means the truck doesn't have to work as hard to maintain speed, which translates into better gas mileage. You'll notice if one gets damaged or falls off, because you’ll feel a slight decrease in efficiency and maybe a little more spray from the road. They also help with stability, especially in crosswinds. You can find a good selection of these at places like Fixparts Online, and they have different styles depending on your trailer’s needs. They're not critical for operation, the trailer will still roll without it, but it’s definitely a component that helps with performance and saves you money in the long run.
